I have a Lennar smart home with a ICS 7150-c12 switch and a R510 access point. My access point is at firmware 200.5.10.0.235 and I tried to update it using the instructions in videos. I tried the iPhone Unleashed app and a couple of browser methods on a wireless laptop. In the app case I get an error "Failed to fetch versions." and in the browser cases the updated versions field never populates. I'm pretty sure the firmware is old and I'd like to update it.
